Balabdaoui and Mohr [1]} have proposed a compartmental model to capture the dynamic of highly age-sensitive epidemics and evaluate the effect of social contact patterns on a load of hospitals and their intensive care units. Stocks et al. [2]} have introduced a model selection process using transmission models subdividing the population into age classes. Pellis et al. [3]} have also suggested a mathematical approach to select between age and household structure in designing a model for an initial, rapid assessment of potential epidemic severity.
